American Airlines is the carrier Mochi and I have used the most for US-domestic cabin pet travel. They accept cabin pets on most flights under 12 hours within the contiguous 48 states, Alaska, Canada, Mexico, and the Caribbean. The carrier goes under the seat in front of you; weight, dimensions, and breed are checked at the gate.
American Airlines's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.

American Airlines limits cabin pet travel to flights of up to 12 hours within select regions. Booking must be made at least 4 hours before departure through Manage Trips or the call centre. The per-flight pet count is capped, so popular routes fill early. Walk-up requests at the gate are refused once the cap is hit.
American Airlines refuses pet travel when ground temperatures exceed 29°C (85°F) at any point on the itinerary, including connecting airports. The temperature embargo runs by forecast, with the airline applying it 24 hours before departure. Brachycephalic breeds get additional scrutiny in summer; some are barred from the hold entirely for the warm-weather months.
Frequently asked
- What is the cabin weight limit on American Airlines?
- In the cabin, your pet plus its carrier must not exceed 9.07 kg.
- How much does it cost to fly a pet on American Airlines?
- On flights within Metropolitan France, American Airlines charges from 200 USD in the hold, one way per pet. Longer routes cost more — price your exact itinerary.
- How far in advance must I book my pet on American Airlines?
- Add your pet to the booking at least 4 hours before departure — do it when you book the ticket, not at the airport.
- What if my flight is delayed past my health certificate validity?
- If the certificate window expires before you board, you'll need a re-issue. Build a 1-2 day buffer between the cert date and departure to absorb minor delays.
- What happens if I forget a document?
- At the destination airport: at best, an extended inspection while you produce backup; at worst, the pet is held in quarantine or returned to origin at your cost. Bring printed copies.
American Airlines charges $125 USD for cabin pets per segment within the US and Canada, and $200 per kennel for hold-bound pets on international routes including Europe and the UK. The fee is per pet, per direction. Military and State Department personnel have a separate pet-shipping rate for international routes through American Airlines Cargo.
American Airlines is a workhorse for US cabin pet travel. Your plan answers three questions before booking: is the flight under 12 hours, is the route within the accepted regions, and is the temperature forecast under the summer embargo threshold. With those locked, AA is one of the more reliable US carriers for cabin pets.
